Usher, Coldplay, Kanye West, Alicia Keys & Others Attend Too

Just hours remain before Jay Z announces to the world his plans for newly acquired streaming service Tidal.

As reported, the mogul held a meeting with music’s biggest stars ahead of the 2015 Grammy Awards to tout his vision for the premium service. By no means editorial rhetoric, Jigga brought out titans such as wife Beyonce, Madonna, Nicki Minaj, Rihanna, Kanye West, and Coldplay. The likes of Usher and Alicia Keys participated via conference web-cam.

So as to continue building buzz ahead of this evening’s announcement, a new video teaser has been released of the gathering.

In serving as Roc Nation‘s most prized asset, it’s no surprise that Rihanna was gifted the royal treatment by the entertainment juggernaut last night.

The Bajan beauty celebrated her 27th yesterday and the Jay Z helmed imprint threw an elaborate surprise party in Los Angeles to mark the occasion.

Perhaps hoping to inspire the star, whose 8th album has been delayed in earnest, organisers invited a host of legitimately talented names such as Beyonce, Naomi Campbell, and ‘Empire’ creator Lee Daniels.
